Endoscope System Configuration

FIG. 1 is a block diagram illustrating a function configuration of an endoscope system according to one embodiment of the disclosure. An endoscope system 1 illustrated in FIG. 1 is used when medical workers, including at least doctors, perform an endoscope surgical operation, an endoscope inspection, or an endoscope treatment on a subject such as a patient, in an operating room 100 in a hospital. The endoscope system 1 includes an endoscope 2, a processor 3, a wireless unit 4, a terminal device 5, a display device 6, a system controller 7, a speech input unit 8, an ultrasonic wave device 9, a pneumoperitoneum device 10, an electric scalpel device 11, a printer 12, a room light 13, an electrically-driven operating table 14, and a wireless power supply device 15.

First, the configuration of the endoscope 2 will be described. The endoscope 2 is inserted into a subject. The endoscope 2 is configured using a rigid endoscope or a flexible endoscope. Based on control by the processor 3, the endoscope 2 irradiates the inside of a subject with illumination light, generates endoscope image data by imaging an area of the inside of the subject which has been irradiated with the illumination light, and outputs the generated endoscope image data to the processor 3. The endoscope 2 includes an imaging element 21 that generates image data by imaging the inside of the subject. The imaging element 21 is configured using an image sensor such as a charge coupled device (CCD) or a complementary metal oxide semiconductor (CMOS), or using an A/D conversion circuit, or the like. Note that the endoscope 2 is connected to the processor 3 by a cable or wirelessly so as to be capable of bidirectional communication. In addition, when the endoscope image data generated by the endoscope 2 is transmitted wirelessly, the endoscope image data may be sequentially transmitted to the processor 3 via the wireless unit 4, described subsequently, or the endoscope image data may be sequentially transmitted via a network N100 to a server 200 which is installed in the hospital and outside the operating room 100.

Next, the configuration of the processor 3 will be described. The processor 3 controls the endoscope 2, performs predetermined image processing on endoscope image data which is sequentially input from the endoscope 2, and makes sequential outputs to the display device 6. The processor 3 includes a video processing unit 31, a communication unit 32, a recording unit 33, a replacement device information recording unit 34, and a processor control unit 36.

The video processing unit 31 performs predetermined image processing on the endoscope image data which is input from the endoscope 2 and makes outputs to the display device 6. Here, the predetermined image processing is synchronization processing, demosaicing processing (when the imaging element 21 is a Bayer array), white balance adjustment processing, y-correction processing, saturation adjustment processing, and format conversion processing, or the like. The video processing unit 31 is configured using a field programmable gate array (FPGA), an application specific integrated circuit (ASIC) and a graphics processing unit (GPU), or the like.

The communication unit 32 is configured using a communication module and performs bidirectional communication with the terminal device 5 according to a predetermined communication standard. Furthermore, the communication unit 32 performs bidirectional communication with the terminal device 5 via the wireless unit 4 or with the server 200, which is installed in the hospital, via the network N100. Here, the predetermined communication standard is wireless fidelity (Wi-Fi) (registered trademark) communication, Bluetooth (registered trademark) communication, and Bluetooth Low Energy (registered trademark) communication (hereinafter simply called “BLE communication”), or the like. For example, in the case of Wi-Fi, a local network is assumed, and where device roles are concerned, there is a relationship between access points and stations and, where the overall connection processing is concerned, the relationship is such that stations are connected to the wireless network whereon the access points are constructed. As an approximate connection sequence, the wireless unit 4, which is an access point, first constructs a wireless network and reports its own network identifier (SSID). Thereafter, the communication unit 32 of the processor 3, which is a station, searches for the reported network identifier (SSID) and connects to the desired network (access point). Because a network of multiple devices is assumed, the coverage is broad, and strict identification steps are followed while considering the problem of interference. Hence, it sometimes takes time to establish a connection. However, data communication enables data to be sent and received with the timing of the respective access points and stations. Note that the communication unit 32 may adopt communication using 4G wireless in addition to Wi-Fi communication. Obviously, the communication unit 32 could also adopt other communication such as communication using 3G wireless, communication using 5G wireless, worldwide interoperability for microwave access (WiMAX) (registered trademark) communication, and infrared communication (infrared data association (IrDA) (registered trademark)) or the like.

Terminal Device Processing

The processing executed by the terminal device 5 will be described next. FIG. 3 is a flowchart illustrating an overview of processing executed by the terminal device 5.

As illustrated in FIG. 3, the terminal device 5 first executes authentication processing that performs authentication of whether or not the user of the terminal device 5 is a registered user who is able to operate the terminal device 5 (step S101). After step S101, the terminal device 5 moves to step S102, described subsequently.

Authentication Processing

Next, the details of the authentication processing described in step S101 of FIG. 3 will be described. FIG. 4 is a flowchart illustrating the details of the authentication processing.

As illustrated in FIG. 4, the authentication unit 602 acquires user information of the terminal device 5 (step S201). Specifically, the authentication unit 602 acquires, from any one of the imaging unit 52, the fingerprint information detection unit 53, and the speech input unit 54, image data obtained by the imaging unit 52 imaging the user of the terminal device 5, fingerprint information for the user as detected by the fingerprint information detection unit 53, and speech data generated by the speech input unit 54, respectively.

Thereafter, the authentication unit 602 determines whether or not the user is a registered user on the basis of the user information of the terminal device 5 and the authentication information recorded by the authentication information recording unit 561 (step S202). Specifically, the authentication unit 602 authenticates whether or not the user is a registered user on the basis of the image data generated by the imaging unit 52 and the authentication information recorded by the authentication information recording unit 561. More specifically, the authentication unit 602 determines whether or not there is a predetermined match rate between the feature points of the face of a user appearing in the image corresponding to the image data generated by the imaging unit 52, and the feature points of the face of a registered user included in the authentication information recorded by the authentication information recording unit 561, and authenticates the user as being a registered user when there is a predetermined match rate, and authenticates the user as not being a registered user when there is not a predetermined match rate. Furthermore, the authentication unit 602 authenticates whether or not the user is a registered user on the basis of the fingerprint information detected by the fingerprint information detection unit 53 and the authentication information recorded by the authentication information recording unit 561. More specifically, the authentication unit 602 determines whether or not there is a predetermined match rate between the feature points of user fingerprint information detected by the fingerprint information detection unit 53, and the feature points of registered-user fingerprint information included in the authentication information recorded by the authentication information recording unit 561, and authenticates the user as being a registered user when there is a predetermined match rate, and authenticates the user as not being a registered user when there is not a predetermined match rate. In addition, the authentication unit 602 authenticates whether or not the user is a registered user on the basis of the speech data generated by the speech input unit 54 and the authentication information recorded by the authentication information recording unit 561. More specifically, the authentication unit 602 determines whether or not there is a predetermined match rate between the feature points of the voice print of the speech data generated by the speech input unit 54, and the feature points of the voice print of a registered user included in the authentication information recorded by the authentication information recording unit 561, and authenticates the user as being a registered user when there is a predetermined match rate, and authenticates the user as not being a registered user when there is not a predetermined match rate. In addition, the authentication unit 602 determines whether or not there is a predetermined match rate between gesture information of a user appearing in the image corresponding to the image data generated by the imaging unit 52, and the gesture information included in the authentication information recorded by the authentication information recording unit 561, and authenticates the user as being a registered user when there is a predetermined match rate, and authenticates the user as not being a registered user when there is not a predetermined match rate. Here, gesture information is the number of times the user blinks, the shape of their mouth, their face and hand actions, and the like, for example. When it is determined by the authentication unit 602 that the user of the terminal device 5 is a registered user (step S202: Yes), the authentication unit 602 allows the user to use the terminal device 5 (step S203).

Thereafter, the display control unit 604 causes the display unit 55 to display a GUI or the like which is capable of receiving user operation inputs (step S204). Note that, although the display control unit 604 causes the display unit 55 to display a GUI or the like which is capable of receiving user operation inputs, the fact that usage of the terminal device 5 is allowed may be reported using a loudspeaker or the like (not illustrated). That is, the display control unit 604 functions as a reporting unit that reports the fact that wireless two-way communication between the processor 3 and the terminal device 5 or wireless two-way communication between the network N100 and the terminal device 5 is possible. After step S204, the terminal device 5 returns to the foregoing main routine of FIG. 3.

When the authentication unit 602 determines in step S202 that the user of the terminal device 5 is not a registered user (step S202: No), the authentication unit 602 disables usage of the terminal device 5 by the user (step S205).

Thereafter, the display control unit 604 disables the display unit 55 or causes the display unit 55 to display a warning (step S206). Note that, although the display control unit 604 disables the display unit 55 or causes the display unit 55 to display a warning, the display control unit 604 may output a warning via a loudspeaker or the like (not illustrated). After step S206, the terminal device 5 returns to the foregoing main routine of FIG. 3.

Returning to FIG. 3, the description of step S102 and subsequent steps will now be resumed.

In step S102, the terminal device 5 executes connection processing to establish a connection with the processor 3 for bidirectional communication therewith (step S102). After step S102, the terminal device 5 moves to step S103, described subsequently.

Connection Processing

Next, the details of the connecting processing described in step S102 of FIG. 3 will be described. FIG. 5 is a flowchart illustrating the details of the connecting processing.

As illustrated in FIG. 5, the connection determination unit 601 first determines whether or not a processor IP address (SSID) and authentication information have been received from the processor 3 via the communication unit 51 (step S301). Here, authentication information is information for requesting an authentication result of the authentication unit 602 which functions as a password for performing wireless two-way communication with the processor 3. When it is determined by the connection determination unit 601 that a processor IP address and authentication information have been received from the processor 3 via the communication unit 51 (step S301: Yes), the terminal device 5 moves to step S302, described subsequently. In contrast, when it is determined by the connection determination unit 601 that a processor IP address and authentication information have not been received from the processor 3 via the communication unit 51 (step S301: No), the terminal device 5 performs this determination at predetermined time intervals (every ten seconds, for example).

Thereafter, the communication control unit 603 causes the communication unit 51 to transmit, to the processor 3, the terminal IP address recorded in the terminal IP address recording unit 562 by the recording unit 56 and the authentication result authenticated by the authentication unit 602 (step S302). In this case, the communication control unit 603 causes the communication unit 51 to transmit the terminal IP address and the authentication result to the access point (the SSID of the processor 3 or the SSID of the wireless unit 4) which the user has pre-selected via the operating unit 57. Note that, although the access point is the processor 3 or the wireless unit 4 in the present embodiment, the terminal device 5 may also be used as the access point. In this case, the communication control unit 603 may transmit, via the communication unit 51, a terminal IP address (SSID) indicating that the terminal device 5 lies within a predetermined range, for example, a Wi-Fi communication range.

In step S303, the connection determination unit 601 determines whether or not the processor IP address received by the communication unit 51 is a connection destination capable of two-way communication with the terminal device 5 (step S303). Specifically, the connection determination unit 601 determines whether or not the processor IP address is the processor IP address (SSID) which the user has selected via the operating unit 57. When it is determined by the connection determination unit 601 that the processor IP address received by the communication unit 51 is a connection destination capable of two-way communication with the terminal device 5 (step S303: Yes), the terminal device 5 moves to step S304, described subsequently. In contrast, when it is determined by the connection determination unit 601 that the processor IP address received by the communication unit 51 is not a connection destination capable of two-way communication with the terminal device 5 (step S303: No), the terminal device 5 moves to step S306, described subsequently.

In step S304, the communication control unit 603 connects the terminal device 5 to the processor 3 so as to enable two-way communication therebetween. Thus, the terminal device 5 assumes a state of being capable of two-way communication with the processor 3.

Thereafter, the display control unit 604 causes the display unit 55 to display a connection completion indicating that the connection with the processor 3 is complete (step S305). Thus, the user is able to intuitively grasp that a state enabling two-way communication with the processor 3 has been assumed. After step S305, the terminal device 5 returns to the main routine of FIG. 3. Note that, although the display control unit 604 causes connection completion to be displayed by the display unit 55, the disclosure is not limited to such a feature, rather, the fact that a connection with the processor 3 is complete may also be output by a loudspeaker (not illustrated) or may be reported by driving a vibrating section (not illustrated) such as a motor, for example.

In step S306, the display control unit 604 causes the display unit 55 to display a connection impossibility to the effect that a connection with the processor 3 is not possible. Thus, the user is able to intuitively grasp that a connection with the processor 3 is not possible. After step S306, the terminal device 5 returns to the main routine of FIG. 3.

Returning to FIG. 3, the description of step S103 and subsequent steps will now be resumed.

When the terminal device 5 and the processor 3 assume a two-way communication state in step S103 (step S103: Yes), the terminal device 5 executes communication operation processing to control the respective parts of the endoscope system 1 by communicating with the processor 3 in response to operations for which inputs are received by the operating unit 57 (step S104). After step S104, the terminal device 5 moves to step S105. In contrast, when the terminal device 5 and the processor 3 do not assume a two-way communication state (step S103: No), the terminal device 5 ends this processing.

Communication Operation Processing

Next, the details of the communication operation processing in step S104 of FIG. 3 above will be described. FIG. 6 is a flowchart illustrating details of the communication operation processing.

As illustrated in FIG. 6, first, when a software program has been received from the processor 3 via the communication unit 51 (step S401: Yes), the terminal control unit 60 updates the software program recorded in the recording unit 56 (step S402). Thus, the terminal device 5 is capable of updating the program for operating the peripheral devices and the processor 3 to the latest program. Furthermore, the software program includes parameters for setting the initial values of the peripheral devices as well as updating the program of the peripheral devices and the processor 3. After step S402, the terminal device 5 moves to step S403, described subsequently. In contrast, when a software program has not been received from the processor 3 via the communication unit 51 (step S401: No), the terminal device 5 moves to step S403, described subsequently.

When an input of a setting request signal requesting setting information has been made from the operating unit 57 in step S403 (step S403: Yes), the communication control unit 603 causes the communication unit 51 to transmit the setting request signal to the processor 3 (step S404). Here, setting information is set parameters which are set by the user from set parameters with initial values for the peripheral devices.

Thereafter, when the communication unit 51 has received setting information from the processor 3 (step S405: Yes), the communication control unit 603 records the setting information in the recording unit 56 (step S406). In this case, the communication control unit 603 may transmit the setting information to the processor 3 via the communication unit 51. The processor 3 is thus capable of automatically setting the set parameters of the peripheral devices to the set parameters which have been set by the user of the terminal device 5 via the system controller 7 on the basis of the setting information. Note that the communication control unit 603 may request the setting information from the server 200 via the communication unit 51 and the wireless unit 4. After step S406, the terminal device 5 moves to step S407, described subsequently. In contrast, when the communication unit 51 has not received setting information from the processor 3 (step S405: No), the terminal device 5 returns to step S404 above.

When an input of a setting request signal requesting setting information has not been made from the operating unit 57 in step S403 (step S403: No), the terminal device 5 moves to step S407, described subsequently.

When, in step S407, an input of an image request signal requesting endoscope image data generated by the endoscope 2 and case image data recorded by the server 200 has been made from the operating unit 57 (step S407: Yes), the communication control unit 603 causes the communication unit 51 to transmit the image request signal to the processor 3 (step S408).

Thereafter, when the communication unit 51 has received endoscope image data and the case image data from the processor 3 (step S409: Yes), the display control unit 604 causes the display unit 55 to display an endoscope image corresponding to the endoscope image data and a case image corresponding to the case image data which have been received by the communication unit 51 (step S410). In this case, when the endoscope image data received by the communication unit 51 is moving image data which is sequentially transmitted, the display control unit 604 sequentially updates, in chronological order, the endoscope image corresponding to the endoscope image data. Furthermore, the display control unit 604 causes the display unit 55 to display the endoscope image and the case image so as to enable a comparison of these images. For example, the display control unit 604 may cause the display unit 55 to display the endoscope image and the case image in parallel, may cause the display unit 55 to display a case image, which has been reduced by a predetermined ratio, by superposing the case image on the endoscope image, or may cause the display unit 55 to display an endoscope image, which has been reduced by a predetermined ratio, by superposing the endoscope image on the case image. After step S410, the terminal device 5 moves to step S411, described subsequently. In contrast, when the communication unit 51 has not received endoscope image data or case image data from the processor 3 (step S409: No), the terminal device 5 returns to step S408 above.

When, in S407, an input of an image request signal requesting endoscope image data generated by the endoscope 2 and case image data recorded by the server 200 has not been made from the operating unit 57 (step S407: No), the terminal device 5 returns to step S411, described subsequently.

When, in step S411, an input of a schedule request signal requesting schedules that include a surgery schedule, a treatment schedule, a rounds schedule, and a hospital discharge schedule, and the like, for a subject, has been made from the operating unit 57 (step S411: Yes), the communication control unit 603 causes the communication unit 51 to transmit the schedule request signal to the processor 3 (step S412).

Thereafter, when the communication unit 51 has received schedule information from the processor 3 (step S413: Yes), the communication control unit 603 records the endoscope image data received in step S410 above in the recording unit 56 in association with a patient rounds time period included in the schedule information (step S414). After step S414, the terminal device 5 moves to step S415, described subsequently. In contrast, when the communication unit 51 has not received schedule information from the processor 3 (step S413: No), the terminal device 5 returns to step S412 above.

When, in step S411, an input of a schedule request signal requesting schedules that include a surgery schedule, a treatment schedule, a rounds schedule, and a hospital discharge schedule, and the like, for a subject, has not been made from the operating unit 57 (step S411: No), the terminal device 5 moves to step S415, described subsequently.

When, in step S415, an input of a resolution setting request signal for setting the resolution of endoscope image data and the resolution of case image data which are received from the processor 3 has been made from the operating unit 57 (step S415: Yes), the communication control unit 603 causes the communication unit 51 to transmit the resolution setting request signal to the processor 3 (step S416). After step S416, the terminal device 5 moves to step S417, described subsequently. In contrast, when an input of a resolution setting request signal for setting the resolution of endoscope image data and the resolution of case image data which are received from the processor 3 has not been made from the operating unit 57 (step S415: No), the terminal device 5 moves to step S417, described subsequently.

When, in step S417, the replacement device information acquisition unit 58 has acquired wireless tag information from the replacement device information recording unit 34 provided in the processor 3 (step S417: Yes), the display control unit 604 causes the display unit 55 to display the wireless tag information (step S418). Thus, a medical worker is able to intuitively grasp a replacement period for replaceable devices in the endoscope system 1. After step S418, the terminal device 5 moves to step S419, described subsequently. In contrast, when the replacement device information acquisition unit 58 has not acquired wireless tag information from the replacement device information recording unit 34 provided in the processor 3 (step S417: No), the terminal device 5 moves to step S419, described subsequently.

When, in step S419, an input of an operating signal for operating peripheral devices has been made from the operating unit 57 (step S419: Yes), the communication control unit 603 transmits the operating signal to the processor 3 via the communication unit 51 (step S420). After step S420, the terminal device 5 moves to step S421, described subsequently. In contrast, when an input of an operating signal for operating peripheral devices has not been made from the operating unit 57 (step S419: No), the terminal device 5 moves to step S421, described subsequently.

When, in step S421, the communication unit 51 has received an operation disabled signal indicating that peripheral devices cannot be operated from the processor 3 (step S421: Yes), the display control unit 604 causes the display unit 55 to display a warning to the effect that operation of the peripheral devices at the user level of the terminal device 5 is prohibited (step S422). After step S422, the terminal device 5 moves to step S423, described subsequently. In contrast, when the communication unit 51 has not received an operation disabled signal indicating that peripheral devices cannot be operated from the processor 3 (step S421: No), the terminal device 5 moves to step S423, described subsequently.

When, in step S423, an instruction signal ending the operation of the endoscope system 1 has been input from the operating unit 57 while performing communication with the processor 3 (step S423: Yes), the terminal device 5 returns to the main routine of FIG. 3. In contrast, when an instruction signal ending the operation of the endoscope system 1 has not been input from the operating unit 57 while performing communication with the processor 3 (step S423: No), the terminal device 5 returns to step S401 above.

Returning to FIG. 3, the description of step S105 and subsequent steps will now be resumed.

When, in step S105, an instruction signal ending the operation by the terminal device 5 has been input from the operating unit 57 (step S105: Yes), the terminal device 5 moves to step S106, described subsequently. In contrast, when an instruction signal ending the operation by the terminal device 5 has not been input from the operating unit 57 (step S105: No), the terminal device 5 returns to step S104 above.

In step S106, the communication control unit 603 records the processor IP address of the processor 3 in the recording unit 56. After step S106, the terminal device 5 ends this processing.

According to the embodiment of the disclosure described hereinabove, the communication control unit 603 allows wireless two-way communication between the processor 3 and the terminal device 5 on the basis of the determination result of the connection determination unit 601 and the authentication result of the authentication unit 602, and hence both efficiency and information security can be taken into account.

In addition, according to the embodiment of the disclosure, when the processor 3 and the terminal device 5 have assumed a state enabling wireless two-way communication, the communication control unit 603 acquires, via the communication unit 51, at least one of a software program and setting information from the processor 3 or from the server 200 which is connected to the network N100, the software program being a program pertaining to the endoscope system 1, the setting information being information relating to various parameters for the peripheral devices constituting the endoscope system 1 which have been set by a registered user, and hence, at all such times, an operation can be performed very quickly by using the terminal device 5 and without setting peripheral device parameters.

Further, according to the embodiment of the disclosure, the display control unit 604 causes the display unit 55 to display an endoscope image corresponding to the endoscope image data and a case image corresponding to the case image data, which have been acquired by the communication control unit 603, so as to enable a comparison of these images, and hence the endoscope image and the case image may be compared while being viewed.

In addition, according to the embodiment of the disclosure, the recording control unit 605 records, in the recording unit 56 in association with endoscope image data, the patient rounds time period included in the schedule information, and hence the user of the terminal device 5 may perform rounds of a patient such as a subject by using endoscope images while performing the rounds.

Furthermore, according to the embodiment of the disclosure, the communication control unit 603 causes the communication unit 51 to transmit a resolution setting request signal for setting, for the processor 3 or the server 200, the resolution of the endoscope image data, and hence the capacity of the endoscope image data can be restricted.

Note that, according to the embodiment of the disclosure, the imaging control unit 606 may activate the imaging function of the imaging unit 52 when the authentication unit 602 has authenticated the user of the terminal device 5 as being a registered user.

Specifically, the communication control unit 603 may cause information for which an input by the operating unit 57 has been received, such as the findings of a user regarding a subject, for example, to be output by the communication unit 51 to the server 200 outside the operating room 100, or the like. Information security can accordingly be secured.

In addition, according to the embodiment of the disclosure, when the user of the terminal device 5 has been authenticated as being a registered user by the authentication unit 602, the communication control unit 603 may cause the communication unit 51 to transmit information for which an input by the operating unit 57 has been received, such as patient cases or treatment content, for example, to the server 200 which is connected to the network N100. Information security can accordingly be secured.

In addition, according to the embodiment of the disclosure, when the wireless unit 4 has received terminal IP address information from the terminal device 5, the wireless unit 4 may transmit, to the terminal device 5, connectivity determination information indicating whether or not wireless two-way communication with the terminal device 5 is possible. Thus, the operation of the endoscope system 1 using the terminal device 5 can be performed via the wireless unit 4. Here, connectivity determination information is a wireless IP address (SSID) of the wireless unit 4 and a password to allow a connection to the wireless unit 4 at this wireless IP address.

In addition, according to the embodiment of the disclosure, when the wireless unit 4 holds connectivity determination information, the wireless unit 4 may establish an automatic connection between the terminal device 5 and the wireless unit 4 on the basis of the connectivity determination information after the terminal device 5 is powered on.
